IP question

[Jakke PNG]

If I know the IP of a site, how can I check what domain name it has. I also know this particular IP has only 1 domain on it. If I type the IP in, it's blank.. but I know that if I type in a the domain name, it will also be blank. Follow me?

I know
IP
I want to know
Domain name

you could use nslookup to see if that IP has a PTR record associated with it..

on a *nix box type:

nslookup[enter]
[ipaddress][enter]

the output looks something like this:

Name: www.paycounter.com
Address: 66.77.141.20


if not, I don't think you can really figure it withough knowing more info or looking at the server config ;)

If KC's suggestion doesn't work, you can try to telnet to the machine from a Unix box. Like this:

unix: telnet IP 80
....
HEAD / HTTP/1.1
..enter twice

See if you see anything there.
